CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/700,885, filed Sep. 11, 2017, now allowed, and is related to U.S. patent application Ser. No. 15/700,898, filed Sep. 11, 2017, entitled “Dynamic Email System,” which are incorporated herein by reference in their entirety.

BACKGROUND

A business often maintains overlapping email addresses across different departments. For example, a subscriber's email address may be simultaneously stored in a sales department and a service department. This creates a situation where subscriber segments collide. This may prevent the business from presenting multiple product marketing messages to an individual subscriber. This is often because an email system is prevented from sending multiple email messages to the same subscriber during a given time period (e.g., the email system may only send two emails per month per email address). This may cause inconsistent and unpredictable send volumes for the different departments.

In addition, this may prevent the business from creating email campaigns that cross sell products and services. For example, the business may want to create an email campaign that markets a product selected by the sales department, and cross sells a service package for that product from the service department. Finally, the business may need to create and send emails manually, especially when the business is restricted from sending additional emails to a subscriber during a given time period. This may require creating and storing different email templates, and manually assigning content from the different departments to an email. This is often tedious, error prone, and computationally intensive.

Thus, what is needed is a dynamic email system that automatically assigns relevant content to an email message for a subscriber that is present in different departments.

DETAILED DESCRIPTION

Provided herein are system, apparatus, device, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for automatically assigning relevant content to an email for a subscriber at the time the email is sent. Further provided herein are system, apparatus, device, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a content engine that automatically assigning relevant content to an email for a subscriber based on a set of content rules and a persona assigned to the subscriber.

FIG. 1 is a block diagram of a dynamic email system 102, according to some embodiments. Dynamic email system 102 includes persona engine 104, scoring engine 106, and content engine 108.

In some embodiments, persona engine 104 may assign a persona record to a subscriber record. As would be appreciated by a person of ordinary skill in the art, a subscriber record may represent a prospect, a customer, or some other type of entity. A subscriber record may include, but is not limited to, a subscriber email address field, an account identifier field, a name field, an account type field, a content score field, a job function field, and a product interest field. Dynamic email system 102 may store a subscriber record in a subscriber record table in a database. As would be appreciated by a person of ordinary skill in the art, the database may be a relational database management system (DBMS).

In some embodiments, dynamic email system 102 may store a persona record in a persona record table in the database. As would be appreciated by a person of ordinary skill in the art, a persona record may represent a subscriber associated with a sales department, a marketing department, an information technology (IT) department, or various other type of department.

In some embodiments, persona engine 104 may select one or more subscriber records from a set of subscriber records for persona record assignment based on a suppression list. In some embodiments, persona engine 104 may skip assignment of a persona record to a subscriber record based on the associated subscriber being present in the suppression list. In some embodiments, the suppression list may include one or more subscribers to which emails have previously been sent.

In some embodiments, persona engine 104 may assign a persona record to a subscriber record based on the subscriber record being associated with either a prospect or a customer. In some embodiments, persona engine 104 may determine whether the subscriber record is associated with a prospect or a customer based on an account type field in the subscriber record.

In some embodiments, where the subscriber record is associated with a prospect, persona engine 104 may determine that the product interest field of the subscriber record is populated. Persona engine 104 may then assign a persona record to the subscriber record based on the product interest field. In some embodiments, where the product interest field is not populated in the subscriber record, persona engine 104 may assign a default persona record to the subscriber record. For example, in some embodiments, persona engine 104 may assign a sales persona record to the subscriber record.

In some other embodiments, where the subscriber record is associated with a customer, persona engine 104 may determine that the subscriber record indicates that the associated customer owns a sales cloud product. Persona engine 104 then determines whether the job function field of the subscriber record maps to a sales focused role. In some embodiments, where the job function field of the subscriber record maps to a sales focused role, persona engine 104 assigns a cross sales persona record to the subscriber record. In some other embodiments, where the job function field of the subscriber record does not map to a sales focused role, persona engine 104 determines whether the subscriber record has an associated propensity to buy (PTB) score.

As would be appreciated by a person of ordinary skill in the art, dynamic email system 102 may track one or more PTB scores for a subscriber record. For example, in some embodiments, dynamic email system 102 may track a product that the subscriber associated with the subscriber record has a propensity to buy. Dynamic email system 102 may then assign a PTB score to the product for the subscriber record. Dynamic email system 102 may store the PTB score in a unsorted staging stable associated with the subscriber record.

In some embodiments, dynamic email system 102 may rank the PTB scores stored in the unsorted staging table for a subscriber record. In some embodiments, persona engine 104 may assign a persona record to the subscriber record based on the persona record being associated with a product having a highest PTB score for the subscriber record. In some embodiments, where there is a tie among PTB scores, persona engine 104 may assign a persona record to the subscriber record based on a hierarchy of products which have a PTB score assigned.

In some other embodiments, persona engine 104 assigns a persona record to the subscriber record based on the subscriber record indicating that the associated customer does not own a sales cloud product. Persona engine 104 then determines whether the product interest field of the subscriber record does not map to a product that the associated subscriber owns. Persona engine 104 then assigns a persona record to the subscriber record based on the product interest field.

In some other embodiments, where the product interest field of the subscriber record does map to a product that the associated subscriber owns, persona engine 104 determines whether a job function field of the subscriber record does not map to a product that the associated subscriber owns. Persona engine 104 then assigns a persona record to the subscriber record based on the job function field.

In some other embodiments, where the product interest field of the subscriber record does map to a product that the associated subscriber owns, and the job function field of the subscriber record does map to a product that the associated subscriber owns, persona engine 104 determines whether there are any products that the subscriber associated with the subscriber record does not own. In some embodiments, if there are products that the subscriber associated with the subscriber record does not own, persona engine 104 assigns a persona record to the subscriber record based on a product hierarchy. For example, persona engine 104 assigns a persona record to the subscriber record based on a product with a highest revenue potential. In some other embodiments, if there are no products that the subscriber associated with the subscriber record does not own, persona engine 104 assigns a default persona record to the subscriber record. For example, persona engine 104 may assign a sales persona record to the subscriber record.

In some embodiments, scoring engine 106 may assign a content score to a content item in a content database. In some embodiments, scoring engine 106 may determine the performance of a content item across different email messages. For example, in some embodiments, scoring engine 106 may determine the cumulative performance of a content item across multiple email messages by evaluating associated subscriber engagement data according to a series of rules.

In some embodiments, a content item may be an offer item (e.g., a proposal to a customer to buy a product or service). The content item may be stored in a content database. As would be appreciated by a person of ordinary skill in the art, the content database may be a relational DBMS.

In some embodiments, scoring engine 106 may assign a content score to a content items based on subscriber engagement data (e.g., click to open rate (CTOR), click rate, open rate, unsubscribe rate, etc.) associated with the content item. As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may assign a content score at periodic intervals, during a maintenance automation, or at various other times. Similarly, as would be appreciated by a person of ordinary skill in the art, scoring engine 106 may recalculate a content score at periodic intervals, during a maintenance automation, or at various other times.

In some embodiments, scoring engine 106 may determine whether a content item in the content database has more than a threshold value of email sends. For example, scoring engine 106 may determine whether a content item in the content database has been sent more than 1000 times. In some embodiments, scoring engine 106 may assign a content score to a content item that has more than a threshold value of email sends. As would be appreciated by a person of ordinary skill in the art, the assignment of a content score to a content item having a threshold value of email sends may ensure that there is a sufficient sample size for ranking the content item among other content items.

In some embodiments, scoring engine 106 may calculate one or more content score metrics for a content item based on various criteria. For example, in some embodiments, scoring engine 106 may calculate a content score metric for a content item based on a CTOR, click rate, open rate, or unsubscribe rate metric.

In some embodiments, scoring engine 106 may rank a content item based on a content score metric. For example, in some embodiments, scoring engine 106 may compare a content score metric for a first content item to a content score metric for a second content item. In some embodiments, based on the difference in content score metrics, the first content item and the second content item may be reranked. In some embodiments, scoring engine 106 may only rank the first content item and the second content item differently, incrementing one rank from high to low where the difference between their content score metrics is statistically significant. As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may determine that there is a statistically significant difference based on calculating a Z score between the first content score metric and the second content score metric. Moreover, as would be appreciated by a person of ordinary skill in the art, scoring engine 106 may rank the content items using various sorting mechanisms.

In some embodiments, scoring engine 106 may further rank a content item based on its content score for a second metric (e.g., click rate). As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may rank content items based on a hierarchy of best performing content score metrics. As would be appreciated by a person of ordinary skill in the art, a user may specify the hierarchy of best performing content score metrics.

In some embodiments, scoring engine 106 may rank content score metrics of content items in reverse by counting the total number of content items being ranked. For example, in some embodiments, the total number of content items may be the top score.

In some embodiments, scoring engine 106 may weigh multiple content score metrics associated with a content item. In some embodiments, scoring engine 106 may multiply the multiple content score metrics associated with the content item by different weights. For example, scoring engine 106 may multiple a CTOR content score metric by a first weight and a click content score metric by a second weight.

In some embodiments, scoring engine 106 may normalize the multiple weighted content score metrics for the content item. In some embodiments, scoring engine 106 may sum the weighted content score metrics and normalize the resulting number so that it falls within a specific range. For example, in some embodiments, scoring engine 106 may normalize the resulting number to fall between 98 and 0, with 98 being the highest score and 0 being the lowest score. In some embodiments, scoring engine 106 may reserve a specific score in the normalized score range (e.g., a highest score for forced content). For example, scoring engine 106 may reserve a score of 99 for forced content.

In some embodiments, scoring engine 106 may evaluate content score metrics on a daily basis. In some other embodiments, scoring engine 106 may evaluate content score metrics on a different timeline. In some embodiments, scoring engine 106 may store the resulting normalized content score with its associated content item in the content database.

In some embodiments, content engine 108 assigns a content item to a subscriber record based on a content score associated with the content item, a persona record assigned to the subscriber record, or one or more characteristics of the content item. Dynamic email system 102, and content engine 108, solve the technical problem of having to manually assign content items for each email generation request from a different part of a business (e.g., different department) (e.g., as described in 501 of FIG. 5 below). In addition, content engine 108 reduces the amount of database requests issued as part of the content assignment process. In particular, in some embodiments, content engine 108 assigns all content items to a subscriber record at one time, and prior to generation of an email based on the content item assignment. In contrast, previous approaches issued multiple database requests at the time of email sending, one for checking for each content item that could possibly be inserted into the email. Content engine 108 reduces these database requests, and therefore reduces computation. This computation reduction further increases the amount of emails that can be sent per unit of time. Finally, content engine 108 reduces storage requirements because only a single email template is needed for insertion of content items. In contrast, previous approaches required maintaining different email templates for use by different parts of the business. In addition to requiring different email templates, each content item may need to be stored in an offer 1 and offer 2 form in a marketing cloud computing system. This increased storage requirements and added complexity. Content engine 108 reduces these storage requirements.

FIG. 2 is a block diagram of content engine 108, according to some embodiments. Content engine 108 includes rules based content assignment engine 202, persona based content assignment engine 204, and affiliated based content assignment engine 206.

In some embodiments, content engine 108 may assign multiple content items to a subscriber record. For example, content engine 108 may assign a first content item (e.g., a main offer), a second content item (e.g., a secondary offer), and a third content item (e.g., an offer for customers only). In some embodiments, content engine 108 may assign different content items based on one or more of a content score associated with the content item, a persona record assigned to the subscriber record, and one or more characteristics of the content item.

In some embodiments, content engine 108 may select a subset of content items in a content database for possible assignment to a subscriber record. In some embodiments, content engine 108 may store the subset of content items in a content pool. In some embodiments, a content pool may include content items from the content database that are eligible for assignment to a subscriber record.

In some embodiments, content engine 108 may select non-viewed content items in the content database for possible assignment to a subscriber record. For example, in some embodiments, content engine 108 may store in the content pool only content items that the subscriber associated with the subscriber record has not viewed in a certain period of time (e.g., the last 90 days). In other words, content engine 108 may only store “fresh” content items in the content pool. As would be appreciated by a person of ordinary skill in the art, content engine 108 may track a number of views of a content item in the content database by subscriber record.

In some embodiments, content engine 108 may select only valid content items in a content database for possible assignment to a subscriber record. In some embodiments, content engine 108 may select only valid content items from the non-viewed content items for possible assignment to the subscriber record. In some embodiments, content engine 108 may store content items marked as “live” in the content pool (e.g., non-expired content items). In some embodiments, content engine 108 may check an expiration date field of a content item to determine if the content item is expired.

In some embodiments, content engine 108 may assign a first content item to a subscriber record based on one or more of a content score associated with the content item, a persona record assigned to the subscriber record, and one or more characteristics of the content item. In some embodiments, content engine 108 may assign the first content item to a subscriber record using rules based content assignment engine 202 and or persona record based content assignment engine 204. In some embodiments, content engine 108 may assign all content items selected by rules based content assignment engine 202 and persona record based content assignment engine 204 to the content pool. Content engine 108 may then rank the content items in the content pool based on one or more priority values and content scores.

In some embodiments, rules based content assignment engine 202 may store content items in the content pool for possible assignment as a first content item to a subscriber record based on a series of rules. In some embodiments, rules based content assignment engine 202 may apply the series of rules in a prioritized order. In some embodiments, rules based content assignment engine 202 may store a content item with a priority value based on a rule in the series of rules that triggered storage of the content item in the content pool.

For example, in some embodiments, rules based content assignment engine 202 may apply the following series of rules. In some embodiments, rules based content assignment engine 202 may store a content item in the content pool based on the content item being forced content (e.g., having a force content flag=“true”). Rules based content assignment engine 202 may add the content item to the content pool along with a first priority value.

In some embodiments, rules based content assignment engine 202 may store content items in the content pool based on the persona record assigned to the subscriber record being a cross sales persona record. Rules based content assignment engine 202 may add the content items to the content pool along with corresponding second priority values.

In some embodiments, rules based content assignment engine 202 may store a content item in a content pool based on the persona record assigned to the subscriber record having its product owned field set to true, and the content item having its upsell flag set to true. Rules based content assignment engine 202 may add the content item to the content pool along with a priority value associated with the particular persona record.

In some embodiments, rules based content assignment engine 202 may store a content item in a content pool based on the PTB content flag of the content item being not null. Rules based content assignment engine 202 may then add the content item to the content pool along with a corresponding fourth priority value based the PTB score.

In some embodiments, persona based content assignment engine 204 may apply a another set of rules. In some embodiments, persona based content assignment engine 204 may apply the another set of rules after rules based content assignment engine 202 completes. In some embodiments, persona based content assignment engine 204 may store one or more content items in the content pool based on the persona record assigned to the subscriber record, and the one or more content items having an age less than or equal to a threshold value (e.g., 30 days old). Persona based content assignment engine 204 may add the one or more content items to the content pool along with corresponding fifth priority values.

In some embodiments, persona based content assignment engine 204 may store one or more content items in the content pool based on the persona record assigned to the subscriber record, and the one or more content items having content scores greater than a threshold value (e.g., top 3 performance scores). Persona based content assignment engine 204 may add the one or more content items to the content pool along with corresponding sixth priority values.

In some embodiments, rules based content assignment engine 202 may store one or more content items in the content pool based on the persona record assigned to the subscriber record, and the job function field of the subscriber record. Persona based content assignment engine 204 may add the one or more content items to the content pool along with corresponding seventh priority values.

In some embodiments, content engine 106 may sort the content items in the content pool based on the assigned priority values and content performance scores. In some embodiments, content engine 106 may assign the highest ranked content item in the content pool to the subscriber record as its first content item (e.g., main offer).

In some embodiments, content engine 108 may assign a second content item to a subscriber record based on one or more of a content score associated with the content item, a persona record assigned to the subscriber record, and one or more characteristics of the content item. In some embodiments, affiliated content based content assignment engine 206 of content engine 108 may assign a second content item to a subscriber record. In some embodiments, content engine 108 may assign all content items selected by the affiliated content based content assignment engine 206 to the content pool. Content engine 108 may then rank the content items in the content pool based on one or more priority values and content scores.

In some embodiments, content engine 108 may remove the assigned first content item stored in the content pool unless one or more rules apply. In some embodiments, content engine 108 may remove content items from the content pool that were assigned by rules based content assignment engine 202.

In some embodiments, content engine 108 may determine that the first content offer (e.g., the main offer) is not forced content (e.g., does not have a forced content flag of “true”). Content engine 108 may then remove content items from the content pool that match the persona record assigned to the subscriber record. In some embodiments, content engine 108 may remove content items from the content pool that match the persona record assigned to the subscriber record. In some embodiments, content engine 108 may store one or more content items in the content pool based on the persona record assigned to the subscriber record being a cross sales persona record. In some embodiments, content engine 108 may add the content items to the content pool along with corresponding second priority values.

In some other embodiments, content engine 108 may determine that the first content offer (e.g., the main offer) has a forced content of “true.” Affiliated content based content assignment engine 206 may then assign one or more content items to the content pool based on their affiliation with the assigned first content item. For example, this may occur if there is no content item marked as forced content. In some embodiments, content engine 108 may add the one or more content items to the content pool along with corresponding first priority values.

In some embodiments, affiliated content based content assignment engine 206 may add additional content items based on a set of rules. For example, in some embodiments, affiliated content based content assignment engine 206 may store one or more content items in the content pool based on being affiliated content with the first content item, and the one or more content items having an age less than or equal to a threshold value (e.g., 30 days old). Affiliated content based content assignment engine 206 may add the one or more content items to the content pool along with corresponding third priority values.

In some embodiments, affiliated content based content assignment engine 206 may store one or more content items in the content pool based on being affiliated content with the first assigned content item, and the one or more content items having content scores greater than a threshold value (e.g., top 3 performance scores). Affiliated content based content assignment engine 206 may add the one or more content items to the content pool along with a fourth priority value.

In some embodiments, affiliated content based content assignment engine 206 may store one or more content items in the content pool based on being affiliated content with the first assigned content item, and the job function field of the subscriber record. Affiliated content based content assignment engine 206 may add the one or more content items to the content pool along with a fifth priority value.

In some embodiments, content engine 106 may sort the content items in the content pool based on their assigned priority values and content performance scores. In some embodiments, content engine 106 may assign the highest ranked content item in the content pool to the subscriber record as a second content item (e.g., affiliated offer).

In some embodiments, content engine 108 may assign a third content item to a subscriber record based on the subscriber record being associated with a customer. In some embodiments, content engine 108 may assign a content item from the content pool based on the content item being tagged as a third content item (e.g., a third offer) (e.g., as described in 516 of FIG. 5 below). In some embodiments, content engine 108 may perform this assignment randomly.

In some embodiments, content engine 108 may determine that the first assigned content item or second assigned content item are available for selection. In some embodiments, content engine 108 may not insert the first and second content items into an email message for the subscriber record if they are unavailable.

In some embodiments, dynamic email system 102 may send an email for each subscriber record containing its associated assigned content items (e.g., a main offer, an affiliated offer, and third offer). As would be appreciated by a person of ordinary skill in the art, dynamic email system 102 may send the emails on demand or at various intervals.

In some embodiments, dynamic email system 102 may generate the email for each subscriber record using an email template (e.g., as described in 514 of FIG. 5 below). In some embodiments, dynamic email system 102 may insert all assigned content items into the email at once based on a single request for all assignments (e.g., as described in 501 of FIG. 5 below). This may reduce the number of network requests need to retrieve content items compared to previous solutions.

FIG. 3 is a flowchart for a method 300 for assigning a persona record to a subscriber record, according to an embodiment. Method 300 can be performed by processing logic that can comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions executing on a processing device), or a combination thereof. It is to be appreciated that not all steps may be needed to perform the disclosure provided herein. Further, some of the steps may be performed simultaneously, or in a different order than shown in FIG. 3 , as will be understood by a person of ordinary skill in the art.

Method 300 shall be described with reference to FIG. 1 . However, method 300 is not limited to that example embodiment.

In 302, persona engine 104 receives a subscriber record. As would be appreciated by a person of ordinary skill in the art, a subscriber record may represent a prospect, a customer, or some other type of entity. A subscriber record may include various fields including, but not limited to, a subscriber email address, account identifier, name, account type, content score, job function, and primary product interest field.

In 304, persona engine 104 determines that the subscriber associated with the subscriber record is not present on a suppression list. For example, persona engine 104 may determine that the email address of the subscriber record is not present on the suppression list.

In 306, persona engine 104 determines that the subscriber associated with the subscriber record is a given type (e.g., a customer or prospect). For example, in some embodiments, persona engine 104 may determine that the subscriber associated with the subscriber record is a customer based on an account type field of the subscriber record.

In 308, persona engine 104 assigns a persona record to the subscriber record based on one or more fields of the subscriber record, e.g., a primary product interest field and a job function field, or a product owned by subscriber record. For example, in some embodiments, where the product interest field is populated in the subscriber record, persona engine 104 may assign a persona record to the subscriber record based on the primary product interest field. In some other embodiments, where the job function field of the subscriber record maps to a sales focused role, persona engine 104 may assign a cross sales persona record to the subscriber record. In some other embodiments, where the job function field of the subscriber record does not map to a sales focused role, persona engine 104 may assign a persona record to the subscriber record based on an associated PTB score.

FIG. 4 is a flowchart for a method 400 for assigning a content score to a content item in a content database, according to an embodiment. Method 400 can be performed by processing logic that can comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions executing on a processing device), or a combination thereof. It is to be appreciated that not all steps may be needed to perform the disclosure provided herein. Further, some of the steps may be performed simultaneously, or in a different order than shown in FIG. 4 , as will be understood by a person of ordinary skill in the art.

Method 400 shall be described with reference to FIG. 1 . However, method 400 is not limited to that example embodiment.

In 402, scoring engine 106 selects a content item in a content database. In some embodiments, a content item may be an offer item (e.g., a proposal to a customer to buy a product or service). The content item may be stored in a content database. As would be appreciated by a person of ordinary skill in the art, the content database may be a relational DBMS.

In 404, scoring engine 106 determines that the content item has more than a threshold number of email sends. For example, scoring engine 106 may determine that the content item in the content database has been sent more than 1000 times.

In 406, scoring engine 106 calculate one or more content scores for the content item based on various metrics. For example, in some embodiments, scoring engine 106 may calculate CTOR, click rate, open rate, and unsubscribe rate content scores for the content item. As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may calculate various other types of content scores for the content item.

In 408, scoring engine 106 ranks the content item among the other content items based on one of its content score metrics. For example, in some embodiments, scoring engine 106 may compare the content score metric for the content item to a corresponding content score metric for a second content item. In some embodiments, based on the difference in content score metrics, scoring engine 106 may rerank the content item with respect to the second content item. In some embodiments, scoring engine 106 may only rank the content item and the second content item differently, incrementing one rank from high to low where the difference between their content score metrics is statistically significant. As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may determine that there is a statistically significant difference based on calculating a Z score between the two content score metrics.

In some embodiments, scoring engine 106 may further rank the content item among the other content items based on a second one of its content score metrics. As would be appreciated by a person of ordinary skill in the art, scoring engine 106 may rank content item based on a hierarchy of best performing content score metrics.

In 410, scoring engine 106 weighs and normalizes the one or more content score metrics for the content item. For example, in some embodiments, scoring engine 106 may multiply the multiple content score metrics associated with the content item by different weights. For example, scoring engine 106 may multiple a CTOR content score metric by a first weight and a click content score metric by a second weight. Scoring engine 106 may then normalize the multiple weighted content score metrics for the content item. For example, in some embodiments, scoring engine 106 may sum the weighted content score metrics and normalize the resulting number so that it falls within a specific range.

In 412, scoring engine 106 may store the resulting normalized content score with the content item.

FIG. 5 is a flowchart for a method 500 for assigning a content item to a subscriber record, according to an embodiment. Method 500 can be performed by processing logic that can comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions executing on a processing device), or a combination thereof. It is to be appreciated that not all steps may be needed to perform the disclosure provided herein. Further, some of the steps may be performed simultaneously, or in a different order than shown in FIG. 5 , as will be understood by a person of ordinary skill in the art.

Method 500 shall be described with reference to FIGS. 1 and 2 . However, method 500 is not limited to that example embodiment.

In 501, content engine 108 receives an email generation request. In 502, content engine 108 receives a subscriber record for assignment of one or more content items from a content database.

In 504, content engine 108 selects non-viewed content items from the content database for possible assignment to the subscriber record. For example, in some embodiments, content engine 108 may store in the content pool only content items that the subscriber associated with the subscriber record has not viewed in a certain period of time (e.g., the last 90 days).

In 506, content engine 108 selects one or more valid content items from the non-viewed content items for possible assignment to the subscriber record. In some embodiments, content engine 108 may check an expiration date field of a content item to determine if the content item is valid (e.g., non-expired). In some embodiments, content engine 108 may store the non-viewed valid content items marked in a content pool for possible assignment to the subscriber record.

In 508, content engine 108 assigns a first content item to a subscriber record based on one or more of a content score associated with the content item, a persona record assigned to the subscriber record, and one or more characteristics of the content item. In some embodiments, content engine 108 assigns the first content item to a subscriber record using rules based content assignment engine 202 and or persona record based content assignment engine 204.

In 510, content engine 108 assigns a second content item to the subscriber record based on one or more of a content score associated with the content item, a persona record assigned to the subscriber record, and one or more characteristics of the content item. In some embodiments, affiliated content based content assignment engine 206 of content engine 108 may assign the second content item to the subscriber record.

In 512, content engine 108 assigns a third content item to the subscriber record based on the subscriber associated with the subscriber record being a customer. In some embodiments, content engine 108 may assign the third content item based on the third content item being tagged (e.g., as a third offer). In some embodiments, content engine 108 may perform this assignment randomly. In 514, dynamic email system 102 creates an email for the subscriber record. In 516, dynamic system 102 sends the email for each subscriber record containing its associated assigned content items.
